The project is an integrated development that includes gas production and processing facilities in the Southern Highlands, Hela, Western, Gulf and Central provinces of Papua New Guinea. Approximately 435 mi of pipeline connect the facilities, which include a gas conditioning plant and liquefaction and storage facilities with capacity of 6.9 mt of LNG per year.

Flooding, minimal pre-existing infrastructure and extremely steep slopes were among obstacles that were overcome in constructing the project. Pipe had to be airlifted in some areas because the soil could not support heavy machinery and lack of infrastructure required construction of supplemental roads, communication lines and a new airfield.

“The project is optimally located to serve growing Asia markets where LNG demand is expected to rise by approximately 165% between 2010 and 2025, to 370 mt per year,” said Duffin.
